Bald Eagles Soar: Alberta Sees Population Boom
26 Jan
Summary
- Bald eagle numbers have significantly increased across Alberta and North America.
- Conservation efforts and pesticide bans helped eagles recover from endangerment.
- Lead ammunition and habitat loss remain significant threats to bald eagles.
Bald eagle populations have seen a remarkable recovery across North America, including in Alberta. Once facing endangerment due to persecution and the widespread use of harmful pesticides like DDT, these birds have experienced a population increase of over 600 percent since 1970. Conservation initiatives, including bans on DDT and legal protections, have been instrumental in this comeback.
Historically, bald eagles were primarily found near mountain rivers and lakes. However, in recent years, they have expanded their habitat to include prairie rivers and even agricultural areas. This expansion is supported by abundant food sources such as fish and waterfowl, and unfortunately, sometimes by scavenging on dead livestock.
Recent citizen science counts, like the Christmas Bird Count in Calgary, have recorded unprecedented numbers, with over 400 bald eagles observed. This signifies a profound success in conservation efforts, transforming the species from nearly impossible to find a few decades ago to a widespread presence today.
